I ordered this model with the prefix SE. I managed to buy for 14 thousand, which is very happy. There is no information anywhere, as well as reviews. Therefore, I am writing for those who have already read everything about the V11, but do not understand how it differs from the V11 SE. There are two differences - battery power (2500 versus 3000 for V11) and the main brush - it is for carpets with V-shaped grooves, but it collected everything perfectly on the laminate. Otherwise, it's a V11 without the SE prefix. Charging from the base and from the vacuum cleaner itself, 3 hours. The button is blocked. Nozzles, like V11, except for the main brush.
